A more thorough explanation:

A port of discharge is a harbor where ships unload their cargo. It is also a place where customs officials are stationed to allow persons and cargo to enter a country. It is also known as a port of entry.

For example, if a ship is carrying goods from China to the United States, the port of discharge would be the harbor where the ship unloads its cargo in the United States. This is where customs officials would inspect the cargo and allow it to enter the country.

Another example would be if a ship is traveling from Europe to South America and stops at several ports along the way. Each of these ports would be considered a port of call, but the port of discharge would be the final destination in South America where the majority of the cargo is unloaded.

Understanding the port of discharge is important for international trade and shipping logistics. It helps ensure that goods are properly inspected and allowed to enter a country legally.
